On page 363 of his Steve Jobs biography, Walter Isaacson tells the story of Jobs meeting a graphical designer in the lobby at Apple after a particularly poor interview:
"The process could be intimidating, but Jobs had an eye for talent. When they were looking for people to design the graphical interface for Apple’s new operating system, Jobs got an email from a young man and invited him in. The applicant was nervous, and the meeting did not go well.
"Later that day Jobs bumped into him, dejected, sitting in the lobby. The guy asked if he could just show him one of his ideas, so Jobs looked over his shoulder and saw a little demo, using Adobe Director, of a way to fit more icons in the dock at the bottom of a screen.
"When the guy moved the cursor over the icons crammed into the dock, the cursor mimicked a magnifying glass and made each icon balloon bigger. “I said, ‘My God,’ and hired him on the spot,” Jobs recalled. The feature became a lovable part of Mac OS X, and the designer went on to design such things as inertial scrolling for multi-touch screens (the delightful feature that makes the screen keep gliding for a moment after you’ve finished swiping)."
